A party hat has a volume of 75 cubic inches . If the radius is 5 inches , what is the height of the party hat?

Answers

The height of the party hat is 2.63 inches.

Given that,

A party hat has a volume of 75 cubic inches.

If the radius is 5 inches,

We have to determine,

What is the height of the party hat?

According to the question,

A party hat has a volume of 75 cubic inches.

If the radius is 5 inches,

The volume of the cone is determined by the formula,

\rm v = \pi r^2(h)/(3)

Then,

The height of the party hat is,

\rm v = \pi r^2(h)/(3)\n\n75 = \pi* (5)^2 * (h)/(3)\n\n75 = 25 * (22)/(7) * (h)/(3)\n\n75 = 25 * 1.14 * h\n\n75 = 28.5 * h\n\nh = (75)/(28.5)\n\nh =2.63

Hence, The height of the party hat is 2.63 inches.

Answer:

About 2.86 inches

Step-by-step explanation:

The formula for the volume of a cone is \pi r^2(h)/(3). Plugging the known numbers into this formula, you get:

75=\pi \cdot 5^2\cdot (h)/(3)

(h)/(3)\approx 0.955

h\approx 2.86 inches. Hope this helps!

Hi help me (2·4)²= this is other (6:2)²+

Answers

Answer:

(2·4)² = 64  /  (6*2)² = 144

Step-by-step explanation:

Follow PEMDAS :

Parenthesis first, so:

2 * 4

==> 8

Then Exponent:

8 ^2

==> 64

(2·4)² = 64

Do the same for (6:2)² :

Parenthesis first :

6 * 2

==> 12

Then Exponent:

12^2

==> 144

(6:2)² = 144

Answer:

1. 64 is the answer.

2. 144 is the answer

Step-by-step explanation:

First, multiply the numbers inside the parenthesis. So

1. 2*4 = 8

2. 6*2 = 12

Next, Use the exponents

1. 8^2

2. 12^2

Finally, solve using exponents.

1. 8^2 = 64

2. 12^2 = 144

So 64 and 144 is the answer.

Hope this helped,

The volume of a cone is 258.9 cubic centimeters. a cylinder has the same base and height as the cone. what is the volume in cubic centimeters of the cylinder

Answers

Volume of a cylinder = A(base)*height

Volume of a cone = 1/3*A(base)*height

Because the base and height of the cylinder and cone are the same, we can write

Volume of the cone = 1/3*A(base)*height =1/3*Volume of the cylinder

Volume of the cone = 1/3*Volume of the cylinder, so

Volume of the cylinder=3*Volume of the cone =3*258.9=776.6 cm³

Volume of the cylinder= 776.6 cm³

Answer:

776.7 cm^3

What is the reading in kwh of the electric meter shown in the exam figure below?

Answers

Answer:

(C)=0631

Step-by-step explanation:

Kwh is the unit of measurement which is equal to the amount of the energy being used or the amount of energy you are using.

In order to get the readings of kwh of the electric meter, take the smallest reading when there are numbers from 0 to 9 and zero is always taken if the meter points between the number 9 and 0.

Hence, from the given meter, the first meter points between 0 and 1, thus reading will be 0 as 0 is the smallest of the two. Next, the reading is between 6 and 7, therefore the reading will be 6. similarly, the rest readings will be 3 and 1. Therefore, the correct reading will be: 0631
What is the reading in kwh of the electric meter shown in the exam figure below?

The answer is letter C. 0631. Always read the dial from left to right. If the dial is in between the numbers, choose the smaller number. If it is between 9 and 0, choose 9.
